The Themis Ultra Scale is designed to maintain stable performance under changing thermal conditions. It incorporates a temperature compensation algorithm and has undergone physical temperature testing to support consistent measurements during normal use.

High-Temperature Usage Scenarios

When using preheated glass carafes for large pours (for example, around 500 g), the scale may occasionally show weight drift even when no items are added or removed.

This behavior is related to the operating environment and does not indicate a malfunction of the scale.

Why Does Weight Drift Occur?

The drift is caused by external heat conduction from the hot vessel into the scale body.
This heat can temporarily affect the strain gauge sensor or the ADC reference voltage, leading to gradual reading changes.

This issue is not caused by internal electronics heating or board-level components.

Recommended Solution

To minimize thermal impact and maintain stable readings, we recommend placing a heat-insulating pad (such as a silicone pad or wooden coaster) between the scale and the hot vessel.

This is currently the most effective and practical solution for high-temperature use cases.

Can the Scale Withstand Brief Exposure to Hot Water or Steam?

Yes. The transparent lid of the Themis Ultra Scale has passed a test in which it remained securely attached after being boiled in 100 °C water for 30 minutes.

Brief exposure to hot water (approximately 1–2 seconds) is acceptable.

However, please note the following:

• Frequent hot water rinsing is not recommended

• The IP67 waterproof rating primarily protects against liquid water

• Water vapor may penetrate the scale and potentially affect internal components

If condensation appears inside or around the transparent cover, this is normal and harmless. Simply wipe it off or allow it to evaporate naturally.

Can the Scale be used for kitchen baking?

Yes. The scale is made with a reinforced, heat-resistant PC shell and internal steel plate. The PC shell conforms to food-grade material standards, making it safe for direct contact with food.
